DEVICE FOR USEIN VIEWING MOTION PICTURES.

application-filed August 9,1923. "Se1ia1NoJ65Q525.

To all whomc'tmay concern:

Be it known that I, ARTHUR I. Comma, a citizen ofthe United Statesot America, and:a resident'o'i' Van WVert, in the county of Van IVert :and State of Ohio,'-have invented a new and Improved Device lor Use in Viewing Motion Pictures, of which the *following is a descriptionf I My invention irelates to a device for use in viewing motion pictures-antl has for an object to provide a device that will 'prevent injury to the eye by eliminating or minimizing the strains incident to such pictures.

More specifically, the invention has for objects to provide a device that may be reversed to View the pictures from either end of the device, the opposite ends being differently formed to adapt it to people wearing glasses or ada ted to more closely conform to the face w en glasses are not worn.

The invention furthermore has for an important object toprovide a device that may be folded into compact form to occupy small compass, whereby the device may be conveniently accommodated in a pocket.

The invention also has in view to provide a device for the indicated purpose reflecting practical considerations with respect to strength with lightness and simplicity of construction. I

The nature at the invention and its distinguishing features and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of practical examples of the invention.

Figure 1 is an elevation of a device for viewmg motion pictures representing my invention in one form;

Figure 2 is a transverse vertical section on a reduce-d scale, the plane of the section being indicated by the line 2-2 in Figure 3;

Figure 3 is a plan view of the device enlarged over the showing in Figures 1 and 2;

Figure 4 is a section at right angles to Figure 2 as indicated by the line 4L4 in.

Figure 3; I

Figure 5 is a view similar to Figure 1 illustrating another form of the invention; Figure 6 is a plan view of the device formed as in Figure 5;

Figure :7 is an elevation showing the invention in still another form( Referringat first more particularly to the invention as illustrated iin Figures 1 to 4, the device comprises two optical tubes 10 connected in this form of the invention by rigid cross, bars 11. A handle 12 is ,pro-

vided andqpivoted at its upper endas at -18 to a keeper-device 'design-atedgenerally by the numeral 1 1 and presentinga=seat :15 and clamp 16 at right anglesito each other,

the former idisposedat the :top of the ad- ;jacent tube 10, said clampiextending vertically. The handle part 12 can thus swing 011 the pivot 13 from a vertical position seated in the clamp 16 as shown in Figure 1 to a horizontal portion on top of the tubes 10 extending across the same as shown in Figures 3 and 4. A second keeper 17 is provided on the second tube 10 of a pair alined with seat 15 to coact in holding the handle part 12 in folded or knocked down position. In connection with the handle part 12 is an extension handle section 18 detachably secured by any suitable means to the handle part 12, the latter being shown as having a socket 19 to detachably receive the upper end oi. the section 18. Both the .handle part 12 and the handle section 18 are advantageously tapered. In order to hold the handle section 18 when the device is assembled in knocked down form, I provide a tubular holding device 20 rigid with the tubes 10 and bridging the same parallel with seat 15 and keeper 17 into which device 20 the handle section 18 may be inserted when detached from the handle part 12.

At one end 21, the two tubes 10 terminate in the same transverse plane so that the pictures may be viewed tl'irough the said end 21 by those wearing glasses. At their opposite ends the tubes 10 have curved end surfaces 22 cOnlorn'iing approximately to the facialformation adjacent the eyes. A person without glasses may thus view the pictures through the curved ends 22 and with the optical tubes close to the face.

In the form shown in Figures 5 and (3 the optical tubes 110 are united by the same cross bars 11 and are formed with plane ends 21 and curved ends 22. In this form of the invention a unitary handle part 112 is provided which is tapered and adapted at its smaller end to enter a vertical sleeve by any approved means.

116 disposed vertically and made rigid with the adjacent tube 110. At the top of the device parallel with the tubes and preferably adjacent to one tube 110 is a second keeper sleeve 115 to receive the handle part 112 when removed from the keeper sleeve 116.

In the form shown in Figure 7 the optical tubes 110 are the same as in the other two forms and with this form of the invention sleeves 115, 116 are provided on one tube. The tubes, however, are pivotally connected I have indicated conventionally tubes connected after the manner of opera glasses, the cross bars 111 being united as at 23 so that the tubes 110 may be swung on the pivot to vary the pupillary distance as for example in adjusting the device to suit either a child or an adult.

I would state in conclusion that while the illustrated examples constitute practical em bodiments of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim:

1. A device for use in viewing motion pictures, comprising optical tubes, a handle comprising separable sections, means to dispose the handle adjacent the side of one of the tubes and in a plane perpendicular to the plane. in which the axes of the tubes lie, means to hold separately the handle sections on the tubes when the device is ,in knocked down form.

2. A device of the class described comprising optical tubes, a handle, and handle receiving keeper sleeves rigid with the tubes and approximately at right angles to each other.

ARTHUR I. OLYMER.
